Hi all, I'm having two problems when using PreRender.
1 – when adding fog, it is not drawn everywhere, there is a border in unexpected places after which there is no fog.
2 – when using PBR textures, in this case a texture with transparency, transparency does not always appear, the entire object is visible with a black background. But this is not always the case, once there is, the second time there is not.
FOG solution: Disable the CPU in the render config
For the trasparency solution you have to do this in the node editor: connect "Alpha" to "Transparency" putting a color inversion node in between.
